. My inve on is fully disclosed in the following The rubber or the like channel I is thus disdescription taken in connection with the accom- I posed i a groove formed by the parts 1 ands and panying drawing in which,"- l2 above described. I M a Fig. 1 is an elevational view of a fragment of Such a groove extends all the way around the cave. Likewise a strip or length of the rubber tion.

During the process of manufacturing or molding the rubber channel I, as at "-41, I embed therein a plurality of anchoring devices Iii-l8,

which. may be variously formed as will presently appear but being generally elongated and embedded in the channel flanges 2 -2 extending from the outer end of the channel flanges as at l9-I9 to a point in the channel flange which in the form of my invention illustrated is approximately halfway from the end of the flange at i9 to the web 3 of the flange.

In the form illustrated in Figs. 2 to 5 inclusive, the devices iii are in the form of a wire bent at the inner end to provide an eye 20 andat the outer and joined as by butt-welding to a wire or head 2|, the bead, when the devices are embedded in the channel flanges, being disposed along the outer termination of the channel flange. The

the mold in which the channel I is formed and during the process of molding the channel, the

devices [9 are embedded therein as illustrated and as above described to make a strip of channel material with the beads 2| thereon and the devices .2l embedded therein.

Such a strip of rubber channel may now be installed in the above described groove of the window frame construction and when the chan nel is bent to conform to the rounded corners of the window, it is prevented from buckling or otherwise becoming distorted by the rigid'metal bead 2| and the d ces" l8 integral therewith and embedded in the rub er. Furthermore, when the a channel is thus installed, it is given a finished and astheticaliy beautiful appearance by the visible bead 2 I and to this end, the bead may be given any desired metal flnish for example, as by chromium plating, or by being lacquered in any desired color.

' In turning a comer with the improved rubber channel above described, the devices ll may take the generally radial positions indicated in Fig. 1.

'- device l8 comprises'an elongated body secured at one end to the bead 2| and having either at its opposite end or throughout its length an eye or other perforation through which the rubber in the molding process may flow to anchor the device in the rubber.

In the form of Fig. 10. the bead re is hexagonal without sacrificing its advantages.

between adjacent elements.

in cross sectional form instead of circular as in the other forms described.

In Fig. 9 a flat'bead 21 is shown having an anchoring device 18 similar to that in Fig. 6."

In Figs. 14 and 15, a relatively flat bead 21 is 5 illustrated. 1 In this form the anchoring devices 28-28 areformed from a continuous piece of wire having depending loops 29-29 joined to the bead 21 by intermediateportion 30 lying flat against the underside of the bead 21. The wire in from 10 which the loops 29 and intermediate portion v are formed may be of rectangular cross section as illustrated in Fig. 2'7 or it may be a round wire 22 as illustrated in Fig. 16.

in the form shown in Figs. 11 and 12, a head 9' 16 .is shown disposed vertically edgewise to provide are formed from a loop of wire but welded at both I its upper ends as at 39 to an edge of the bead 35 and having a loop at 40 at its opposite end.

In the modification of Fig. 13, the bead 35 may have devices 18 similar to those of Figs. 2 to 5 i inclusive.

It will thus appear that my invention may be embodied in numerous forms and, modifications and my invention is not limited to the modifications illustrated and described inasmuch as many other forms and modiflcations'may be devised within the scope and spirit of my invention While I have described the channel employed in my invention as molded, it will be understood 5 that this term in the specification and claims comprehends channels made by other processes such for example as extruding Processes.

While I have illustrated and described my invention asapplied to a window frame channel in which a glass pane may be supported and may slide in the well known manner, my invention has other applications. For example, the channel of my invention may be employed to circumscribe and flnish the outer edges of an article such as an automotive vehicle windshield. In this con- 45 nection the channel of rubber or the like bendable material may be a true-channel in cross-section or may be of other generally channel form. In this and in other uses, not identified strictly a with a window framewindow guiding channel, the advantages of my invention whereby a bead may be secured to the rubber or like material and may bend therewith in conforming the material to the desired shape, may be enjoyed. g

I claim:

1. As, an article of manufacture adapted to be associated with a bendable molded rubber or like channel during the manufacture of the same, a bendable strip of head material and a. longitudinal series of elongated anchoring elements extending laterally therefrom and joined to the bead strip on longitudinally spaced portions of lesser extent than the spaces between adjacent elements.

-2. As an article of manufacture adapted to be u associatedwith a bendable molded rubber or like on longitudinally spaced portions thereof of longitudinal extent at least as small as the spaces
